GASOLINE DISPENSING PUMP Filed Aug. 16, 1928 3 Sheets-Sheet 3 Patented Mar. 25, 1936 PATENT OFFICE WALDO F. PEREZ, OF JACKSONVILLE, FLORIDA GASOLINE-DISPENSING ZPUMI Application filed August 16, 1928. Serial No. 300,064.

The present invention is directed to im provements in gasoline dispensing pumps.

The primary object of the invention is to provide a device of this character so constructed that gasoline can be dispensed without the service of an attendant.

Another object of the invention is to provide a device of this character so constructed that upon the insertion of a coin of the proper denomination a lever will be interlocked with the valve mechanism to simultaneously discharge gasoline from one bowl, while another bowl is being refilled.

Another object of the invention is to provide a device of this character constructed and arranged in such manner that the operating lever will be maintained in an inoperative condition to prevent operation of the valve mechanism until a coin of the proper denomination has been deposited in the apparatus.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the pump.

Figure 2 is a side view, partly in section.

Figure 3 is a sectional view on line 33 of Figure a.

Figure 4 is a side View, partly in section, of the valve mechanism and coin controlled apparatus.

Figure 5 is a face view of the valve pit.

Referring to the drawings, 1 designates a conventional form of pump stand in which is extended the gasoline supply pipe 2 leading from the storage tank, not shown, the gasoline being forced through said pipe by com- 0 pressed air, as usual.

Mounted in the stand is a casing 8 formed from complementary circular sections 4 and 5, the confronting faces thereof being provided with packing rings 66 and 7 for effectively packing the valve disk 8 rotatable in said casing. The valve disk is fixed to the shaft 9 which is rotatable in the packed bearings 1010 of the sections, one end of said v shaft having a pinion 11 fixed thereto, the

purpose of which will appear later.

The valve disk 9 is provided with a pair of diametrically disposed passages 12 and 13.

Supported upon the stand are gasoline containing bowls 14 and 15, and leading from the bowl 14 are pipes 16 and 17, the pipe 16 connecting with the casing at the point A and has its lower end alined with the upper end of the pipe 18 disposed upon the opposite side of the casing and having communication with the upper end of the inlet pipe 2, the pipe 18 being connected also with the inlet pipe 2.

The pipe 17 has its lower end connected to the casing at the point B and in alinement with the upper end of the pipe 19 upon the opposite side of the casing, the latter pipe connecting with the discharge pipe 20.

Leading from the bottom of the bowl 15 are pipes 21 and 22, the former being connected at its lower end to the casin at the point C and in alinement with the upper end of the pipe 28 disposed upon the opposite side of the casing, said pipe 23 being connected to the inlet pipe 2. p

The pipe 22 is connected to the casing at the point D and is alined with the pipe24 upon the opposite side of the casing, said pipe being connected with the discharge pipe 20.

A coin receiving drum 25 is employed and has fixed centrally thereof a shaft 26 journaled in the sides 2727 of the coin chute 28. 80. This drum is provided with coin receiving pockets 29, four in number, said pockets having inclined bottom walls 30 in order that the coins will roll fully within the pockets and stop against the end walls 31 thereof.

These pockets are capable of being successively brought into registration with the coin entrance chute 82 carried by the wall of the pump stand.

A lever 33 is provided for rotating the drum and has its lower end provided with an abutment S l which has formed. integral therewith spaced arms 35 adapted to span the drum. said arms havin their lower ends provided withbearings 36 forlooselyengagingthe shaft 26 in order that the lever can be swung freely.

The chute 28 has a bracket b7 carried there by and connecting the bracket and lever is a coil spring 38, which normally holds the lever in its inoperative position in the slot 39 formed in the stand, there being a rubber.

bumper 40 in the upper end of the slot to absorb the shock incident to the rebound of the lever when released.

Fixed to the shaft 26 is a gear 4:1 which meshes with the pinion 11, the gear ratio being such that when the gear is rotated onequarter revolution the disk valve 8 will make one-quarter revolution.

When a coin of the proper denomination is deposited in the chute 32 it will roll therefrom into the pocket in registration therewith, a portion of the coin projecting from the slot in order that the abutment 34 will engage the projected part of the coin to interlock the lever and drum so that when the lever is rocked the drum and valve will be compelled to make one-quarter revolution after which the lever is released and returns to its inoperative position under the influence or" the spring 38. V

It, will, of course, be understood that the pockets will be brought selectively into registration with the chute 32.

Assuming that the disk valve 8 is in the position as shown in Figure 4 and the passages 12 and 13 are in registration with the opposed ends of the pipes 17 and 19 and pipes 21 and 23, respectively, gasoline under pressure in the pipe 2 will flow into the pipe 23, through the passage 13 into the pipe 21 and into the bowl 15 to fill the same. At the same time fuel from the bowl 14 passes through the pipe 17 through the passage, 12, pipe 19 and into the discharge pipe 20 to the tank filling hose 42.

When the disk valve is again rotated onequarter revolution the passage 12 registers with the opposed ends of the pipes 16 and 18 while the passage 13 registers with the op- V posed ends of the pipes 23 and 2 1, thus permitting gasoline from the pipe 2 to how through the pipes 18 and 16 t5 refill the bowl 14, while the contents of the bowl 15 is being discharged throughthe pipe 22, passage 13,

and pipe 24to the filling hose. 7

It will be seen that when one bowl is'being emptied, the other is being refilled.

43 adapted to successively engage a contact a coin into a pocket of the drum for engagement with the abutment of the lever.

2. A coin controlled mechanism comprising a chute including sides, a shaft ournaled in said sides, a drum fixed to the shaft, radially disposed coin receiving pockets formed in the drumand including inclined bottom Walls, said pockets having one of their ends closed by end walls for limiting the movement of coins therein, a bracket carried by the chute, an actuating lever having an abutment, arms depending from the abutment,

and spanning the drum, said arms having their lower ends pivot-ally engaged with the shaft, a spring connecting the lever and bracket, said abutment being adapted to engage a coin deposited in a pocket to rotate the drum upon swinging the lever in one direction, said spring serving to swing the lever in a reverse direction when released.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be ap- 7 parent to those skilled in the art, without further description, and-it will be understood that various changes in the size, shape and proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advan tages of the invention.
